[PATCH] ip: Make errors direct to "list" instead of "show"

[PATCH] ip: Make errors direct to "list" instead of "show"

[Yedaya Katsman]

The usage text and man pages only have "list" in them, but the errors
when using "ip ila list" and "ip addrlabel list" incorrectly direct to
running the "show" subcommand. Make them consistent by mentioning "list"
instead.

That is because ip command treats "list" and "show" the same.
Would it be better to do the same in all sub commands?

I'm not sure what else you're talking about changing, I couldn't find
anywhere where a "show" is referenced in output. Do you mean treating
"show" and "list" the same everywhere?

Almost all of iproute utils allow list, show, or lst.

You found a couple of places that may not.
Perhaps this will fix it.

Subject: [PATCH] ipila: allow show, list and lst as synonyms

Across ip commands show, list and misspelling lst are treated
the same.
